Linx procedure

The regulation of the crystal structure of oxygen evolution cocatalyst (OEC) is a promising strategy for enhancing the photoelectrochemical efficiency of photoanodes. However, the prevailing regulating approach typically requires a multistep procedure, presenting a significant challenge for maintaining the structural integrity and performance of the photoanode. Herein, FeOOH with a local disordered structure is directly grown on a CdIn2 S4 (CIS) photoanode via a simple and mild sonochemical approach. By modulating the localized supersaturation of Ni ions, ultrasonic cavitation induces Ni ions to participate in the nucleation and growth of FeOOH clusters to cause local disorder of FeOOH...

Minimally invasive thyroidectomy (MIT) is increasingly being used for the thyroid tumors. The comparison of bilateral axillo-breast approach robotic thyroidectomy (BABART) with other MIT has not yet led to a unified conclusion with regard to surgical outcomes. To conduct a systematic review and meta-analysis of the literature on the surgical outcomes of BABART compared with MIT. We performed a systematic search in PubMed, Web of Science, Embase and Cochrane Library database for randomized control trials (RCTs) and non-RCTs that compare BABART to MIT...

BACKGROUND: The magnetic sphincter augmentation (MSA) procedure is an effective treatment for gastroesophageal reflux disease (GERD). Adverse events requiring MSA device removal are rare, but the true prevalence and incidence may be underestimated. METHODS: Retrospective study on a prospectively collected database. Patients who underwent MSA procedure between March 2007 and September 2021 in two tertiary-care referral centers for esophageal surgery were included...

Although it is uncommon, gastroesophageal reflux disease can present after Roux-en-Y gastric bypass, and it is usually related to technical errors. Hiatal hernia, a narrow calibrated gastrojejunostomy and a long gastric pouch are all factors associated with the development of pathologic gastroesophageal reflux. Techniques are available to treat this condition, such as fundoplications with the gastric remnant, gastropexy to the arcuate ligament, teres ligament repair, or sphincter augmentation with the LINX device...

INTRODUCTION: Gastro-oesophageal reflux disease (GORD) is a chronic progressive disease, associated with substantial clinical and economic burden. Proton pump inhibitors (PPIs) are considered first-line treatment; however, there are concerns around the long-term impact of their usage. Surgical treatment with Nissen fundoplication can be considered but, because of the potential side effects, few patients undergo surgery and there remains a substantial therapeutic gap within the current treatment pathway...

INTRODUCTION: Emergency department (ED) visits and readmissions following benign foregut surgery (BFS) represent a burden on patients and the health care system. The objective of this study was to identify differences in ED visits and readmissions before and after implementation of an early postoperative telehealth visit protocol for BFS. We hypothesized that utilization of telehealth visits would be associated with reduced post-operative ED and hospital utilization. METHODS: An early postoperative telehealth protocol was initiated in 2020 at an academic medical center to provide a video conference within the first postoperative week...

Magnetic sphincter augmentation (MSA) is an alternative surgical treatment for gastroesophageal reflux disease; however, >1.5 T magnetic resonance imaging (MRI) is contraindicated for patients who have undergone MSA with the LINX Reflux Management System (Torax Medical, Inc. Shoreview, Minnesota, USA). This drawback can impose a barrier to access of MRI, and cases of surgical removal of the device to enable patients to undergo MRI have been reported. To evaluate access to MRI for patients with an MSA device, we conducted a structured telephone interview with all diagnostic imaging providers in Arizona in 2022...

PURPOSE: We aim to review and quantitatively compare laparoscopic Toupet fundoplication (LTF), Nissen fundoplication (LNF), anterior partial fundoplication (APF), magnetic augmentation sphincter (MSA), radiofrequency ablation (RFA), transoral incisionless fundoplication (TIF), proton pump inhibitor (PPI), and placebo for the treatment of GERD. A number of meta-analyses compared the efficacy of surgical and endoscopic procedures for recalcitrant GERD, but considerable debate on the effectiveness of operative strategies remains...

BACKGROUND: Patients with medically intractable GERD after laparoscopic sleeve gastrectomy (LSG) have limited surgical options. Fundoplication is difficult post-LSG. Roux-en-Y gastric bypass may be used as a conversion procedure but is more invasive with potential for serious complications. Magnetic sphincter augmentation (MSA) is a less invasive GERD treatment alternative. The objective of this study was to assess safety and efficacy outcomes of MSA after LSG. METHODS: The primary outcome of this observational, multicenter, single-arm prospective study was the rate of serious device and/or procedure-related adverse events (AEs)...

Introduction: With the advent of minimally invasive techniques, laparoscopic Nissen fundoplication and Toupet partial fundoplication have been very successful in the management of GERD. In the past 10 years, a number of very attractive new technologies have entered the market around therapeutic GERD-management such as Transoral Incisionless Gastroplication, other endoscopic plication techniques, and the implantation of the magnetic sphincter augmentation (MSA). These new technologies are excessively promoted by the respective companies, propagating their techniques as causing fewer side effects...

Short-chain fatty acids (SCFAs) are volatile fatty acids produced by gut microbial fermentation of dietary nondigestible carbohydrates. Acetate, propionate, and butyrate SCFA measures are important to clinical and nutritional studies for their established roles in promoting healthy immune and gut function. Additionally, circulating SCFAs may influence the metabolism and allied function of additional tissues and organs. The accurate quantification of SCFAs in plasma/serum is critical to understanding the biological role of SCFAs...

BACKGROUND: Anti-reflux surgery (ARS) has known long-term complications, including dysphagia, bloat, and flatulence, among others. The factors affecting the development of post-operative dysphagia are poorly understood. We investigated the correlation of intra-operative esophagogastric junction (EGJ) characteristics and procedure type with post-operative dysphagia following ARS. METHODS: Robotic ARS was performed on 197 consecutive patients with pathologic reflux utilizing EndoFLIP™ technology...

Magnetic sphincter augmentation using the LINX® device is a minimally invasive surgical option for patients with gastroesophageal reflux disease. An estimated 30,000 devices have been implanted worldwide. Device removals and erosion are identified risks. The objective of this analysis is to explore the procedure evolution with an emphasis on the removals and associated characteristics that may guide future clinical practice. The Manufacturer and User Facility Device Experience and Ethicon's complaint databases were queried for all surgical device explants since January 2013...

Background and study aims  Endoscopic treatment has markedly improved the high morbidity and mortality in patients with upper gastrointestinal tract leakage. Most procedures employ either covered self-expanding metal stents (SEMS) or endoscopic vacuum therapy (EVT), both with good clinical success but also with concomitant significant shortcomings inherent in each technique. A newly developed device, the VACStent, combines the fully covered SEMS with a polyurethane sponge cylinder anchored on the outside...

Background: Laparoscopic Nissen fundoplication is considered the current gold standard of surgical treatment of gastroesophageal reflux disease. Magnetic sphincter augmentation with the LINX® device was developed as a less technically challenging alternative that has proven to be a safe and effective surgical antireflux procedure. Despite rapid adoption of the robotic platform in many areas of general surgery, no studies have compared laparoscopic and robotic approaches to placement of the LINX device. This retrospective study is the first to compare the robotic platform with the laparoscopic approach for minimally invasive LINX placement...

OBJECTIVE: We aimed to quantify the contribution of pneumoperitoneum on compliance of the esophagogastric junction (EGJ) during anti-reflux surgery. BACKGROUND: Compliance of the EGJ is reduced with anti-reflux surgery. EndoFLIP® planimetry can be used to assess dynamic changes of EGJ compliance intraoperatively. It is unclear how pneumoperitoneum impacts intraoperative measurements by EndoFLIP® and the implications thereof on validity of the results. Therefore, determining variability in EndoFLIP® measurements based on pneumoperitoneum is warranted to establish guidelines to interpret clinical outcomes...

OBJECTIVE: To quantify the contribution of key steps in antireflux surgery on compliance of the EGJ. BACKGROUND: The lower esophageal sphincter and crural diaphragm constitute the intrinsic and extrinsic sphincters of the EGJ, respectively. Interventions to treat reflux attempt to restore the integrity of the EGJ. However, there are limited data on the relative contribution of critical steps during antireflux procedures to the functional integrity of the EGJ. METHODS: Primary antireflux surgery was performed on 100 consecutive patients with pathologic reflux...

Gastroesophageal reflux disease (GERD) is characterized by abnormal reflux of gastric content into the esophagus, pharynx, respiratory tract and oral cavity. In recent years, there has been a significant increase of the incidence of this disease, that significantly aggravates quality of life of the population. The 'gold standard' for treating GERD is anti-secretory therapy with proton pump inhibitors (PPIs). However, up to 40% of patients are unresponsive to PPIs even after dose adjustment. Advantages and disadvantages of modern surgical approaches for this pathology are reviewed...

BACKGROUND: Magnetic sphincter augmentation with the Linx® system is a novel laparoscopic procedure for the treatment of gastro-esophageal reflux disease (GERD). Only few data are available regarding the impact of Linx on high-resolution manometry (HRM) variables. METHODS: The prospectively collected database of patients who underwent Linx procedure at a single institution was queried. All patients who completed pre- and postoperative HRM, GERD health-related quality of life (GERD-HRQL) questionnaire, and functional outcome swallowing scale (FOSS) questionnaire were included in the study...

BACKGROUND: Medication-refractory gastroesophageal reflux disease (GERD) is sometimes treated with laparoscopic Nissen fundoplication (LNF); however, this is a non-reversible procedure associated with important side effects and the need for repeat surgery. Removable magnetic sphincter augmentation (MSA) devices are an alternative, effective, and safe treatment option for such patients who have some lower esophageal sphincter function. The objective of this study was to assess the economic impact of introducing MSA technology (i...
